Radiofrequency

March, 2020 Minimally invasive treatments

What is Radiofrequency? The use of electric current to treat pain since 1931 began with the treatment of trigeminal neuralgia, and then in the 1970s Sluter invented a modified Radiofrequency wave that produced the same amount of energy.

Radiofrequency was first used in 1974 to treat pain. Its use was initially limited to cervical and lumbar diseases, but with the introduction of the new cannula in 1981 it was possible to control lesion size. Since then, a wide range of chronic pain problems have been treated with this method. With this technique, if the lesion is properly treated, there will be a very long period of pain relief. There are two types of radiofrequency modes used in intron International: pulse and conventional.

Pulsed RF Radio Frequency

Radiofrequency pulse has been accepted in pain control since 1970. In this mode, high voltage radiofrequency current is used for a short time (20 ms) and a silent phase cut off causes the temperature to decrease and ultimately keep the tissue temperature below 42. As a result, tissue destruction does not occur. The electrical fields created by PRF can affect the neuronal membranes, altering synaptic signals, modulating neural activity and rapidly altering electrical fields. The radiofrequency method operates with minimal invasion and target selection. It can also be done on an outpatient basis. Doing so can prevent more aggressive methods at higher costs. Its use is in blocking and modulating (and not destroying) sensory or motor activity.

Conventional RF:

Conventional Radiofrequency : an electrode that travels through the RF, is targeted to the nerve and is destroyed by the heat generated. This technique destroys the target nerve. This method is used in cases where the nerve is only sensory and has no function other than pain transmission. Examples include: RF knee genicular nerves, trigeminal nerve, vertebral facet joints nerves, and disk  decompression.
